Pieceworker → It is formed from "piece" (from Old French *piece*, meaning a part or fragment) and "worker" (from Old English *weorc*, meaning to work). A pieceworker is someone who is paid for each piece of work they complete, rather than a fixed salary.
Think of a 'piece' as a part of work and a 'worker' as someone who does that work. A pieceworker is someone who earns money for each part they complete.
